We have previously mentioned, on a number of occasions, the strategy adopted by the city of Boston to tackle the issues of climate change and rising sea levels: instead of just building levees and seawalls, the city is focused on building with the natural environment, by creating parks, wetland areas, and so on, to mitigate the impact of flooding. However, urban development projects at these sites will also make them much more expensive, ensuring only wealthier people are able to live there – a fairly standard type of gentrification. But what of the existing communities in these places? Will they be forced to move? And will their new homes also be protected against the risks of flooding? It is this “climate-driven” gentrification that Boston’s chief of environment, energy and open space is keen to avoid.
